I’ve been browsing, searching, reading regarding charging the Tesla based on available solar power, but there are many different topics on this subject and I don’t get a good overview of what is working good. Therefore this post and I hope the community can help.
Like many others I want to charge the Tesla based on available solar energy controlled by Home Assistant. What is good integration or what is a good automation script for this.
My situation:
- Home Assistant installed and up and running,
- Tesla integration installed and working perfectly,
- Goodwe integration for solar power monitoring, working perfectly,
- Car charger is a bit old and is from New Motion, no Home Assistant integration.
- P1 meter installed and working perfectly. HA is monitoring the power consumption/production.
What I would like to achieve:
- Car is plugged in into the New Motion charger, when the solar is generating above X watts, the car is being charged.
- Switch to charge from solar or from grid (in case I need the car the next day).
Questions, challenges:
- When I inserted the plug from the New Motion, the car start charging immediately. How can this be controlled if I want to charge from solar?
- If the Tesla is instructed to change the charging current regularly and/of maybe even enabled/disabled (if there is no solar power), Would this damage the car, the batteries? How can this be prevented?
Looking forward to feedback and suggestions? Thanks for the support.
